Metal expansion joints are heavier and should call for special managing and transportation criteria.
fifteen. Use two wrenches when tightening bolts. When tightening the again up rings of rubber flanges, tighten bolts in cross pattern sequence until finally the rubber flange bulges uniformly amongst the back again up ring plus the adjoining pipe flange.
Whilst splicing or signing up for the finishes on the barrier, “stagger” the overlaps from the products to forestall thickness Create-up.
Metal expansion joints can face up to high temperature and pressure when compared with rubber expansion joints for pipes.
We recommend that a visible inspection is carried out promptly on receipt of shipping and delivery on the Expansion Joint to make certain that it hasn't been damaged through shipment.
Stainless steel expansion joints should not be confused with stainless steel flex connectors, which are hose-and-braid-style connectors which has a stainless steel braided product on the skin. They are able to deal with lateral motion and vibration in pipe and devices joints.
Installation of rubber expansion joints is usually more simple due to their lighter fat and bigger flexibility.
Negligible Compression: Compared with rubber, metal joints have restricted compression abilities but are excellent for dealing with axial motion.
Pressure check should be performed based on the stated exam specifications on the drawing and/or maybe the tag plates here about the Expansion Joint.
For a guideline, rubber joints are twenty five% to 50% than metal joints. Rubber joints never require further gasketing and, in many cases, are mounted quickly by 1 or 2 Males with no utilization of special dealing with tools. Metal joints should be serviced often to insure the flange gasket remains to be intact instead of deteriorated.
Be sure that mating flange surfaces are clean, and that misalignment is nominal. If piping is badly away from alignment, Mason or Mercer can furnish alternative expansion joints with this particular initial offset inbuilt.
The delicate, adaptable rubber can take the impact of tough particles devoid of breaking or failing prematurely. But choose the appropriate rubber compound for your personal certain abrasive product.
Tend to be the bellows and other moving components around the Expansion Joint free of charge from foreign objects like insulating material?
Additive producing strategies are increasingly being explored to supply complex bellows geometries with improved exhaustion life and decreased pressure concentrations.
